* (Theme: Environment & Cities):The line graph shows the variations in the levels of carbon emissions caused by three different sectors of transportation (private cars, buses, and trains) in a North African city over a 20-year period between 2005 and 2025.Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The line graph illustrates how much carbon dioxide was released by private cars, buses and trains in a North African city between 2005 and 2025, measured in thousands of tonnes.

public coaches were the only sector to finish below their starting level. In 2005, emissions from cars stood at roughly 120 thousand, which was triple the figure for buses at approximately 40 and twelve times the railway level of a mere 10. Over the following decade, the car total climbed steadily to a high of 180 in 2015, because vehicle ownership expanded rapidly. After that,

, it fell back to around 150 by the end of the period, probably as cleaner engines became widespread. The bus sector followed a different path. Having risen slightly to 55 in 2010, it dwindled to just 35 two decades after the start, so their contribution shrank in both absolute and relative terms. Rail emissions, meanwhile, changed little until 2015 but

surged to about 25, as new lines attracted commuters away from the roads.
